Sir Ian Wilmut, the scientist who led the team that cloned Dolly the sheep in 1996, has died at 79. The University of Edinburgh, where he served as a professor before his 2012 retirement, announced his passing today.
his passing today. Dolly was the first successful cloning of a mammal from an adult somatic cell, demonstrating the viability of somatic cell nuclear transfer . The controversial milestone helped pave the way for today’s research on regenerative medicine.
Born near Stratford-upon-Avon in 1944, Wilmut discovered an interest in biology while at school in Scarborough; he later switched his major at the University of Nottingham from agriculture to animal science, kicking off the work he would be most known for. His Ph.D. studies at the University of Cambridge foreshadowed his later breakthroughs, focusing on “the preservation of semen and embryos for freezing.
Wilmut’s work at The Roslin Institute in Edinburgh continued to push the boundaries of animal genetics. He strived to create modified sheep that would produce milk with proteins that could treat human diseases. A year before Dolly, he successfully cloned two lambs whose cells were taken from sheep embryos.Dolly’s successful birth in 1996 marked the first time a mammal was successfully cloned from an adult cell.
Wilmut moved to the University of Edinburgh the following decade, focusing on using cloning to make stem cells for regenerative medicine. He was knighted in 2008 and retired in 2012. Wilmut was diagnosed with Parkinson’s in 2018 and became a patron of a new research program at the university working to slow the disease’s progression with next-gen therapies.
